Problems solved by technology

[0002] Chemical fertilizer is the largest material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations, chemical fertilizers account for 40-60% of the increase in yield. However, the production time shows that due to the nature of the fertilizer itself and the soil The impact of environmental conditions and agricultural measures, etc., the utilization rate of chemical fertilizers is very low

Abstract

The peanut planting is suitable for soil with soft soil quality, favorable water retention property and abundant organic matters. According to the characteristics, multiple soil conditioners, such as shell powder, diatomite, medical stone powder and the like are adopted, and organic fermentation substances are compounded and used as the coating component of the fertilizer granules. The inside core is composed of chemical mineral constituents coated by a coating agent mainly prepared from the resin; the resin is slowly degraded after entering the soil layer to form a porous structure and slowly release the inside mineral elements, thereby avoiding frequent fertilizer application. Peanuts need water, but are not tolerant to water. The over waterlogging influences the air permeability, so Kiselgel A is added; and the Kiselgel A can be used for defibrination, and can adsorb water after entering the soil layer. The improved soil is loose, and is beneficial to expansion and growth of peanuts, thereby enhancing the yield.

Description

technical field [0001] The invention relates to a high-efficiency slow-release fertilizer for peanut planting and a preparation method thereof, belonging to the technical field of slow-release functional fertilizer for peanut planting in fertilizers. Background technique [0002] Chemical fertilizer is the largest material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations, chemical fertilizers account for 40-60% of the increase in yield. However, the production time shows that due to the nature of the fertilizer itself and the soil Due to the impact of environmental conditions and agricultural measures, the utilization rate of chemical fertilizers is very low. The waste of nutrient resources caused by the low utilization rate of fertilizer nutrients in China is astonishing. According to statistics, the annual production and application of nitrogen fertilizer in China is about 20 million tons, and the ...
